Uninstall
Plugins are uninstalled using the Plugin Manager (figure 1.25). This can be opened using the Plugins () button in the Toolbar, or by going to the top level menu:
Utilities | Manage Plugins... ()
Figure 1.25: The plugin manager with plugins installed.
The installed plugins are shown in the Manage plugins tab of the plugin manager. To uninstall, select the plugin in the list and click Uninstall.
If you do not wish to completely uninstall the plugin, but you do not want it to be used next time you start the Workbench, click the Disable button.
When you close the dialog, you will be asked whether you wish to restart the workbench. The plugin will not be uninstalled until the workbench is restarted.
